Elevated serum calcium to 10.7, but now normal? - Hyperparathyroidism?

[Caliz24]

Hi there - I am a 24 year old female with a history of fibromyalgia/chronic pain (w/ many of the symptoms of hyperparathyroidism). I went in for a physical a couple of weeks ago and for the first time ever, had a high calcium of 10.7. The Dr. repeated the test and today it was normal at 9.4.

I did a lot of research when I first saw that it was elevated and I was convinced that I had hyperparathyroidism after reading about the symptoms and others' experiences. Also, I heard a high calcium is never normal! Does this happen? Is it possible for my calcium to bounce back to normal and still have HPT? My Dr. said my calcium was normalized and nothing further needed to be done. So I'm assuming I'm going to have a hard time convincing them for any further testing such as PTH and checking my calcium again.

Any ideas? Why would I have a high calcium just once?

The Parathyroid.com website is very informative. Here is an excerpt from one of their articles -Hyperparathyroidism Diagnosis: Diagnosing Parathyroid Disease.

"However, it is quite rare for people to have high calcium levels in their blood... and not have a parathyroid tumor.

It is common for patients with hyperparathyroidism (parathyroid disease) to have calcium levels that are high one time it is checked, and normal the next time it is checked. ALL patients with hyperparathyroidism will have calcium levels that change from day to day, week to week, month to month. Most patients with hyperparathyroidism have calcium levels that fluctuate from high to slightly high, to high-normal.    Fluctuating levels of calcium is one of the '10 Parathyroid Rules of Norman'"
